Application led May 21.,

To all whom it may concern:

Be it known that l, CARL J. Mrrsim, a citizen of the United States, residing at Howell, in the county of Vanderburg and State of Indiana, have invented a new and useful Stove, of which the following is a specification.

This invention relates to heating stoves.

The .object is to provide a stove of this character wherein fresh air is taken through the-top of the stove, under damper control, and passed interiorly of the stove through the products of combustion, becomiiig highly heated, and introduced over the bed of coals within the firepot, mingling with the flames and the smoke to produce intense heat, thus resulting in economy of fuel and a greater heat radiation than in ordinary stoves.

A full and complete understanding of the invention may be obtained from` a consideration of the following detailed description taken in connection with the accompanying drawing for-ming part of this application with the understanding, however, thatv the invention is not confined to any strict conformity with the showing of the drawing,`but may be changed and modifiedu'so long as such changes and modifications marit no material departure from the salient features of the invention as expressed in the appended claims. v

In the drawing, in which similar reference characters designate corresponding parts throughout the several figures,

Figure 1 is a. vertical sectional view throughl the `improved stove, the section being` taken through the doors thereof; l

ig. 2 is a similar sectional view taken at right angles to Fig. l; p

Fig. 3 is a top plan View, partly in section; Y

Fig. a is adetail perspective view of the water container `to be used in connection with the stove. 1

In stoves of the class to which the present invention relates, the object sought has been to furnish a continuous supply of fresh air directly over the fire bed in order that la sufficient quantity of oxygen maybe present t0 produce proper heat. This has ordinarily been `done by conducting the fresh air from i the sides of the stoves, thus necessitating the use of short flues'A or conduits which, while supplying the necessary amount of fresh'air, conducted or deposited the same over the Specification of Letters Patent.

fire in a relativelycold condition, thus acting not only to retard rcombustion but to reduce the amount "of heat radiated by the stove.

The present invention contemplates the employment of relatively longair conducting nues or conduits extending from the top of the stove, almost throughout the entire length of the same and on the interior thereof, to a point directly over and around the margins of the fire box, theair during such extended passage, becoming thoroughly heated and finding exit during its route through a plurality of ports which serve to deposit the air at increasing temperatures into the flames and heat during its downward passage until the lowermost exit is reached directlyat themargin of the. lire box.

The stove comprises the drum or casing l, which may be formed of a tubular casting of appropriate metal or it may be constructed of suitable heavy sheet metal forming a cylindrical casing of any desired dimensions. This drum is supported upon a fire pot 2 in any desired manner, said fire pot, in turn, resting upon a base member 3, preferably rectangular in form. in ash pit l is provided having the usual door 5. Base member 8 is adapted tol be supported upon ordinary stove legs 6. A. grate 7 is located Patenten sept. e, assi.

as usual at the lower part of the fire pot, and p the latter may be lined with fire brick as indicated in dotted lines at 8. All the above is of the ordinary construction and may be varied as desired. l

Located a relatively short distance below the top circumferential edge of the drum l, a stationary or permanent head 9 is suitably secured, said head being imperforate and forming a tight closure for the upper end of the drum. An upstanding tube 10 communicates'with the interior of the drum adjacent to the rear thereof and extends somewhat above the upper edge of the same, the said tube being preferably oval in cross section and provided with a port or orice 11, just abovevthe head 9, for a purpose to be described.

A removable head or cover l2 is adapted to rest upon the upper edge of the drum 1,

and is provided with a downwardly extending flange'l 1n `surrounding Vrelation to the l, drum, and forms an air-tight closure there-` for, the cover l2 being provided with a corresponding up-standing tube 14 capable of 'fwall of the oven 24 there isformed a baille sliding over and surrounding the firstnamed tube 10, and forming a suitable connection for the usual smoke pipe 15.V

The'space coniined between the two heads 9 and 12 respectively forms an air Vd lstributing chamber 16, communication with which is had with the atmosphere through the medium of a damper plate 17, preferably of circular formation, and centrally pivoted to a closure plate or lid 18, having a depending flange fitting within va corresponding opening formed at the center of the cover 12. The lid 18 which is readily removable from its seat in the cover 12, is provided with a series of openings arranged circumferentially around the pivot of the same, and adapted to be uncovered by a corresponding series of openings or apertures 19 formed in the damper plate 17 in the usual manner, a greater or lesser amount of opening beingreadily obtainable by reason of the registering relation of the said openings, the damper plate being adapted to Vbe swung about its pivot by means of a suitable handle 20.

A'series of air conduits or iiues 21 formed of suitable metal and comprising three sides of a rectangle, are adapted to be secured to the interior walls of the drum 1 as by bolts 22, said flues 21. having their upper open ends communicating with the air distributing chamber` 16, and their lower open ends located at the lower end ofthe said drum 1 in close proximity to the upper ends of the lire bricks.

The conduits 21, which may be of `any other form in cross section, are provided along their opposite side walls with a series of vroutlets 23, which serve to distribute the heated fresh air directly over the fire, the

vsame being drawn through the conduits 21 by reason of the upward draft of the products of combustion through the vsmoke pipe 15.

A bake oven 24, preferably rectangular in cross section, comprising side walls, a top and bottom wall, and a rear wall 25 located in spaced relation to the rear wall of the drum 1,V is suitably supported over the fire pot, a short distance below the permanent head 9. The oven is open at the front of` the drum 1, and is adapted to be closed by a suitably hinged door 25at which may be swung down to forni a shelf when open. u VLocated a shortdistance below the bottom platef26, preferably integral with the oven and extending to the rear edge thereof. The baffle plate is connected to the bottom of the oven by side walls co-extensive therewith,

land the space confined between the same constitutes a cold air passage,"open at the frontland rear ends and controlled by a suitable slide damper 27 of ordinary-construction.. The rear end of the cold air passage is in spaced relation to the rear wall ofthe drum so that the air passing there through may find ready outlet to intermingle with the Vheat and pass up the smoke pipe 15.

The fuel feed door 28 is located immediately below the damper 27 in the usual location at the front of the drum-1, and it will be seen the several operable parts are within easy reach.

1n Fig. l of the drawingthere is illus# trated a removable water heating reservoir 29 made of suitable metal, and in the form of a tight rectangular box of the proper dimensions to easily slide into the bake oven 24, after the door Y'25a is removed from its hinges for the purp-ose.

The water reservoir is provided with an Vopening 30 in its top wall, and has a filling opening 31 in its front wall surrounded by a guard 32 to facilitate the pouring of water into the same, and a faucet 33located at the bottom of the front. wall in order that hot water may bedrawn 01T when desired.

The port 11, which is open at all ltimes and connects the chamber 16 with the smoke pipe 15 serves, when lighting a fire in the stove, to drawV oi'f and'up the pipe 151all smo-ke and gases which may arise through the conduits 21 and otherwise escape into the room, the draft being suflicient to overcome such tendency. y

F rom the foregoing it will beseen that a simple, cheaply manufactured and'easily opY` erated heating stove. has been provided, which, by reason of the conduits 21, will 'opyerrate to distribute super-heated fresh air di rectly over the fire to the'best advantage to secure intense heat from the combustion with great economy in the consumption of fuel.
